Interesting how people have such a thing about noise - provided it doesn't modulate with the signal I have zero problems with such being part of the picture. What was the "uh-oh" moment in the review was:

As the melody ascended there was also the slightest reduction of the upper-frequency glare that would sometimes slip into the picture with the JC 3.

That's what I would be chasing, there's the remanents of the real demon, for me at least ...

There's more info here and here about the negative inductance trick KSTR used in that thread he linked - theory, calculations etc. Don't be put off by the time machines and flux capacitors in the first link - it's just a bit of humour along the way, he gets to the point eventually.

They emphasize the overload margin (although at 1kHz only) of this pre and I find this correct.
How is it that even today there are phono preamplifier specs that do not include max (*) input voltage (or overload margin ref some V).

(*)In the past, max input voltage was the voltage just before clipping, 1% to 3% THD area.
